30 gauge. Normally I use 6 wraps on a 2.5 mm drill bit for 1.5 ohms.
It wont work in that atty unless you are really really good at working small.
(I don't recommend trying this)
It would take 5 parallel wraps of 34 gauge.
I'll look into that atty and see of a better coil geometry is possible.
Edit: nope
